In electronic design automation, a design rule is a geometric constraint imposed on circuit board, semiconductor device, and integrated circuit (IC) designers to ensure their designs function properly, reliably, and can be produced with acceptable yield. Design rules for production are developed by process engineers based on the capability of ...
Physical verification is a process whereby an integrated circuit layout (IC layout) design is verified via EDA software tools to ensure correct electrical and logical functionality and manufacturability. Verification involves design rule check (DRC), layout versus schematic (LVS), XOR (exclusive OR), antenna checks and electrical rule check ...
PCB-Investigator provides features for PCB design and manufacturing, supporting various file formats like ODB++, Gerber, and IPC-2581. [6] It includes tools for design rule checks (DRC) and other analyses to verify compliance with industry standards. The software also offers 3D visualization of PCBs and supports scripting for task automation ...
CircuitMaker supports design rule configuration and real time design rule checking. Some advanced features, including differential pair routing, interactive length tuning, [23] and polygon pour management, are also available. [24] Production files can be exported directly, although an external Gerber viewer must be used to check the exports.

Modern PCB design software typically provides "interactive routers"—the drafter selects a pad and clicks a few places to give the EDA tool an idea of where to go, and the EDA tool tries to place wires as close to that path as possible without violating design rule checking (DRC). Some more advanced interactive routers have "push and shove ...
NEW YORK (Reuters) -The Biden administration plans to unveil a new rule next month that will expand U.S. powers to stop exports of semiconductor manufacturing equipment from some foreign countries ...
This is where an LVS check is used. The need for such programs was recognized relatively early in the history of ICs, and programs to perform this comparison were written as early as 1975. [ 1 ] These early programs operated mainly on the level of graph isomorphism , checking whether the schematic and layout were indeed identical.
